Abstract
Official abstract text for this publication.
A display device includes a light-transmitting portion, a display light source arranged at an inner side of the light-transmitting portion, and a housing including an opening. The housing accommodates the display light source and the light-transmitting portion is arranged in the opening. The light-transmitting portion includes a transparent plastic base member, a first color exhibiting layer containing dye or pigment, and a second color exhibiting layer containing a filler made of a cold mirror thin film. The first color exhibiting layer has a transmittance of 20% or more for light having a specific wavelength. The second color exhibiting layer has a reflectance of 80% or less for light having a wavelength not absorbed by the dye or the pigment of the first color exhibiting layer and a transmittance of 60% or more for light having a wavelength absorbed by the dye or the pigment of the first color exhibiting layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device, comprising: a light-transmitting portion arranged on an electromagnetic-wave-transmissive panel; a display light source arranged at an inner side of the light-transmitting portion, the display light source being configured to emit light to the light-transmitting portion to illuminate and display the light-transmitting portion; and a housing including an opening, the housing accommodating the display light source, the light-transmitting portion being arranged in the opening, wherein the light-transmitting portion includes a transparent plastic base member, a first color exhibiting layer containing dye or pigment, and a second color exhibiting layer containing a filler made of a cold mirror thin film reflecting visible light and transmitting infrared light, the first color exhibiting layer has a transmittance of 20% or more for light having a specific wavelength, and the second color exhibiting layer has a reflectance of 80% or less for light having a wavelength not absorbed by the dye or the pigment of the first color exhibiting layer and a transmittance of 60% or more for light having a wavelength absorbed by the dye or the pigment of the first color exhibiting layer. 2. The display device according to claim 1 , wherein a reflecting portion configured to facilitate reflection of light is arranged on a surface of the housing that is opposed to the light-transmitting portion. 3. The display device according to claim 1 , wherein the light-transmitting portion has a transmittance of 60% or more for infrared light and an attenuation factor of 3.0 dB or less for millimeter waves.
